Nitrile rubber also known as nbr or buna n is one of the most commonly used sealing elastomers due to its resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.Ul style"margin-top0px;padding-top 5px; padding-bottom 5px;" acrylonitrile content the acrylonitrile (acn) content of the polymer chains can be varied from 18 to 50. Lower acn content gives better low-temperature properties but poorer fuels and polar lubricants. Higher acn content gives poorer low-temperature properties but improved fuels and polar lubricants resistance. Standard nbrs typically have 34 acn content. Cure system sulfur-cured standard nitriles are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures. Peroxide-cured nitriles have better heat resistance and lower compression sets but are more expensive and more difficult to process.
